violince
What any nearby listeners might be driven to from hearing horrendously-poor fiddle-playing.
Jack Benny was actually quite an accomplished musician (you have to be a good instrument-performer in order to "do well at playing poorly" --- i.e., play said instrument in a humorously-awful way that will make your listeners laugh), and so it's unlikely that any members of his audience would have felt the need to resort to violince.
